1、畢業(yè)設(shè)計(jì)說明書題目名稱：采煤機(jī)搖臂低速區(qū)軸承振動(dòng)特性與故障分析院系名稱：機(jī)械設(shè)計(jì)制造及其自動(dòng)化班級(jí)：學(xué)號(hào)：學(xué)生姓名：指導(dǎo)教師：2015年5月摘要機(jī)械工業(yè)是一個(gè)國(guó)家的重要產(chǎn)業(yè)，機(jī)械工業(yè)的發(fā)展無(wú)時(shí)不刻都在影響著國(guó)家經(jīng)濟(jì)的發(fā)展，人類的進(jìn)步離不開機(jī)械工業(yè)的發(fā)展。在全球經(jīng)濟(jì)發(fā)展的大環(huán)境下，中國(guó)各個(gè)行業(yè)被其他國(guó)家的先進(jìn)技術(shù)影響的同時(shí)，越來(lái)越多的外國(guó)企業(yè)和品牌傳播到中國(guó)已經(jīng)成為現(xiàn)實(shí)。在新的市場(chǎng)需求的推動(dòng)下，對(duì)采煤機(jī)搖臂低速區(qū)軸承進(jìn)行改良和優(yōu)化是當(dāng)務(wù)之急。有大型采煤機(jī)設(shè)備企業(yè)對(duì)設(shè)備的安全指標(biāo)的有著一定生產(chǎn)的嚴(yán)格要求。在生產(chǎn)設(shè)備的企業(yè)，充分考慮到在設(shè)備運(yùn)行中可能出現(xiàn)的問題，從而減少噪
2、聲污染引起的振動(dòng)或不當(dāng)操作設(shè)備的現(xiàn)象等。國(guó)內(nèi)采煤機(jī)搖臂低速區(qū)軸承的研發(fā)及制造要與全球號(hào)召的低效經(jīng)濟(jì)、安全穩(wěn)定主題保持一致。采煤機(jī)搖臂低速區(qū)軸承的發(fā)展與人類社會(huì)的進(jìn)步和科學(xué)技術(shù)的水平密切相關(guān)。全套圖紙，加本次設(shè)計(jì)的題目是采煤機(jī)搖臂低速區(qū)軸承振動(dòng)特性與故障分析，在設(shè)計(jì)過程中，主要對(duì)采煤機(jī)搖臂低速去軸承結(jié)構(gòu)方案的確定和相關(guān)組件的計(jì)算和設(shè)計(jì)，重點(diǎn)完成了采煤機(jī)搖臂低速區(qū)軸承振動(dòng)特性與故障分析。首先，完成了對(duì)搖臂減速器的傳動(dòng)比分配，轉(zhuǎn)速及傳遞功率的計(jì)算，5其次，完成了采煤機(jī)搖臂殼體內(nèi)一軸、二軸、三軸、四軸、五軸和各軸傳動(dòng)齒輪的設(shè)計(jì)及校核，簡(jiǎn)單介紹了行星輪系的裝配關(guān)系確定和強(qiáng)度校
3、核。再次，重點(diǎn)對(duì)搖臂低速區(qū)軸承的振動(dòng)特性進(jìn)行詳細(xì)分析。最后，對(duì)采煤機(jī)搖臂低速區(qū)軸承進(jìn)行了三維建模，有限元分析。關(guān)鍵詞：機(jī)械工業(yè)；采煤機(jī)搖臂低速區(qū)軸承；設(shè)計(jì)；有限元分析；5AbstractWithdevelopmentofallkindofsciencetechnologyandglobaleconomy,Pneumaticmanipulatorisaautomateddevicesthatcanmimicthehumanhandandarmmovementstodosomething，aslocanaccordingtoafixedproceduretomoving
